Hi-Yield Weed & Grass Stopper with Dimension will not kill existing poa annua. It is a fantastic product and one of many we carry that would do a great job of preventing poa annua germination when applied at the right time. It can be hard to get rid of poa annua in lawns with a post-emergent, depending on what kind of turfgrass you may have. If you want to let us know what turf you have we can see if we have a post-emergent product that would work for you.
